Do containers need backup?

Containers are breaking backups around the world, but there are steps you can take to make sure that the most critical parts of your container infrastructure are protected against the worst things that can happen to your data center.

At first glance it may seem that containers don’t need to be backed up, but on closer inspection, it does make sense in order to protect against catastrophic events and for other, less disastrous eventualities.

Container basics

Containers are another type of virtualization, and Docker is the most popular container platform. Containers are a specialized environment in which you can run a particular application. One way to think of them is like lightweight virtual machines. Where each VM in a hypervisor server contains an entire copy of an operating system, containers share the underlying operating system, and each of them contains only the required libraries needed by the application that will run in that container. As a result, many containers on a single node (a physical or virtual machine running an OS and the container runtime environment) take up far fewer resources than the same number of VMs.
